An environmentally friendly waste battery recycling extrusion device

Abstract

The invention discloses a waste battery recovery and squeezing device for environment protection. The waste battery recovery and squeezing device for environment protection comprises an alkali solution supply tank, a discharging soaking tank, a cutting machine, a crushing and compacting assembly and the like. By adoption of the waste battery recovery and squeezing device for environment protection, the problem that in the prior art, dangers such as explosions happen in the subsequent cutting and compacting or heating process of waste batteries due to insufficient discharging of the waste batteries is solved; the problems of low discharging efficiency, waste caused by insufficient discharging, and insufficient utilization of an alkali solution of an existing battery discharging soaking method according to which batteries are generally directly soaked in an and then fished for next operation are solved; and the problems that in the prior art, a vertical stamping method is used for battery compaction, but various elements in batteries cannot be effectively recovered through the method; the batteries can be damaged in the stamping process, a large quantity of residues fall out of a machine, and consequentially, unified storage is difficulty; and the compaction effect based on vertical stamping is poor, and gaps still exist between the batteries in the left-right direction are alsosolved.

Description

technical field [0001] The invention relates to the technical field of waste battery recycling, in particular to a waste battery recycling extrusion device for environmental protection. Background technique [0002] In recent years, with the rapid development of electric vehicles and large-scale energy storage markets, the output of lithium-ion power batteries, which currently occupy the largest market share, has also grown rapidly, and the number of waste lithium-ion power batteries produced will inevitably show a blowout type of rise. Waste lithium-ion power batteries contain a large amount of cobalt, lithium, nickel, manganese, copper, aluminum, etc. There is a shortage of non-ferrous metal elements and toxic and harmful substances such as lithium hexafluorophosphate and polyvinylidene fluoride, so it is of great significance to recycle and harmlessly treat them. However, the traditional battery treatment methods are currently the main treatment methods for waste batter...

Problems solved by technology

[0007] In order to overcome the shortcomings of the existing technical solutions, the present invention provides an environmentally friendly waste battery recycling extrusion device, which not only solves the problem of incomplete discharge of traditional waste batteries, but also the danger of explosion in the subsequent shear compaction or heating process. problem, and solved the existing battery immersion discharge, which usually uses a direct method to immerse in alkaline solution, then salvage it, and carry out the next step of operation, but this immersion method not only has low discharge efficiency but also incomplete discharge, and alkali It also solves the problem that the existing battery compaction adopts vertical stamping method. Firstly, this method can not effectively recover many elements in the battery, and secondly, the battery will be damaged a lot during the stamping process. The residue falls outside the machine, which makes unified storage difficult. Second, the compaction effect of vertical stamping is not complete, and there is still a gap between the left and right sides of the battery.
